Outcome Measures
Primary Outcome Measures
- Visual Acuity [1 week to 10 months]
Uncorrected Visual Acuity (UCVA) and Best Spectacle Corrected Visual Acuity (BSCVA) at distance (4 meters) and near at preferred distance and measured by logMAR. LogMAR is the "logarithm of the minimum angle of resolution". It is a unit of measure for visual acuity (VA). A lower logMAR value indicates better visual acuity.
Secondary Outcome Measures
- Contrast Sensitivity [1 week to 10 months]
Contrast sensitivity is the measurement of how faded an image may become before it is indistinguishable. Contrast sensitivity was measured in photopic, mesopic, and mesopic with glare conditions at the following spatial frequencies: 1.5, 3, 6, 12, and 18 cpd (cycles per degree). Contrast sensitivity is measured in log units. A higher value for the logarithmic units translates to better contrast sensitivity.
